# Writing your first Django app, part 6

This tutorial begins where Tutorial 5 left off. We’ve built a tested Web-poll application, and we’ll now add a stylesheet and an image.

Aside from the HTML generated by the server, web applications generally need to serve additional files — such as images, JavaScript, or CSS — necessary to render the complete web page. In Django, we refer to these files as “static files”.

For small projects, this isn’t a big deal, because you can just keep the static files somewhere your web server can find it. However, in bigger projects – especially those comprised of multiple apps – dealing with the multiple sets of static files provided by each application starts to get tricky.

That’s what `django.contrib.staticfiles` is for: it collects static files from each of your applications (and any other places you specify) into a single location that can easily be served in production.

## Customize your app’s look and feel

First, create a directory called `static` in your `polls` directory. Django will look for static files there, similarly to how Django finds templates inside `polls/templates/`.

Django’s `STATICFILES_FINDERS` setting contains a list of finders that know how to discover static files from various sources. One of the defaults is `AppDirectoriesFinder` which looks for a “static” subdirectory in each of the `INSTALLED_APPS`, like the one in `polls` we just created. The admin site uses the same directory structure for its static files.

Within the `static` directory you have just created, create another directory called `polls` and within that create a file called `style.css`. In other words, your stylesheet should be at `polls/static/polls/style.css`. Because of how the `AppDirectoriesFinder` staticfile finder works, you can refer to this static file in Django simply as `polls/style.css`, similar to how you reference the path for templates.

Static file namespacing

Just like templates, we might be able to get away with putting our static files directly in `polls/static` (rather than creating another `polls` subdirectory), but it would actually be a bad idea. Django will choose the first static file it finds whose name matches, and if you had a static file with the same name in a different application, Django would be unable to distinguish between them. We need to be able to point Django at the right one, and the easiest way to ensure this is by namespacing them. That is, by putting those static files inside another directory named for the application itself.

Put the following code in that stylesheet (`polls/static/polls/style.css`):

polls/static/polls/style.css

    li a {
        color: green;
    }

Next, add the following at the top of `polls/templates/polls/index.html`:

polls/templates/polls/index.html

    {% load static %}

    <link rel="stylesheet" type="text/css" href="{% static 'polls/style.css' %}" />

The `{% static %}` template tag generates the absolute URL of static files.

That’s all you need to do for development. Reload `http://localhost:8000/polls/` and you should see that the question links are green (Django style!) which means that your stylesheet was properly loaded.

## Adding a background-image

Next, we’ll create a subdirectory for images. Create an `images` subdirectory in the `polls/static/polls/` directory. Inside this directory, put an image called `background.gif`. In other words, put your image in `polls/static/polls/images/background.gif`.

Then, add to your stylesheet (`polls/static/polls/style.css`):

polls/static/polls/style.css

    body {
        background: white url("images/background.gif") no-repeat right bottom;
    }

Reload `http://localhost:8000/polls/` and you should see the background loaded in the bottom right of the screen.

Warning

Of course the `{% static %}` template tag is not available for use in static files like your stylesheet which aren’t generated by Django. You should always use relative paths to link your static files between each other, because then you can change `STATIC_URL` (used by the `static` template tag to generate its URLs) without having to modify a bunch of paths in your static files as well.

These are the basics. For more details on settings and other bits included with the framework see the static files howto and the staticfiles reference. Deploying static files discusses how to use static files on a real server.
